CTA gives me the fear, it seems so difficult. I only spend about 10% of my time doing UK tax, so ADIT seems more useful. Not sure if is beyond me though! So hard to gauge the level of the exams until you actually start studying for them.

My tip would be to look at past papers and see what is closest to your current work. My experience is that these exams are easier to pass if you are working in the area. But CTA is very wide ranging so I'd be very impressed by ADIT as I think it's quite specialised. It's also easy to get CTA study materials. Good luck!

Thank you Floppity and Auntidote. I had a really good look at the pp, ADIT is definitely more useful for my current job. If I ever was to go into practice then CTA would probably be better, but for the foreseeable it seems ADIT is the way to go.

Work would be paying for everything, and they are of the opinion that any study isn't essential in order to progress, but it is a bonus IYSWIM.

Thanks for all the help! I think I'll start ADIT in 2015, give myself some time to properly prepare and bring my skills up.
